Short Bio

I was born in Maranhao, Brazil, and had my first taste of computing at 7, copying BASIC programs into a tk-3000-IIe. I recieved his Undergraduate and Master degree in Computer Sciences at the State University of Campinas (UNICAMP), where I was also a founding member of the Legonians, a multi-disciplinary fellowship for the exploration of play in its electronic and non-electronic forms.

From 2005 to 2010, I pursued my graduate studies in the University of Tokyo, Japan, as a MEXT scholar under the supervision of Professor Hitoshi Iba at his Genetic Programming Laboratory. My research in this period focused on studying problem representations in Genetic Algorithms for specific domain applications, in particular Financial Portfolio Optimization.

In 2011, I was hired as a Pos-doc researcher under a CAPES grant at COPPE-UFRG, and performed research on the use of Differential Evolution for classification and visualization of Leukemia Data with professor Carlos Eduardo Pedreira.

From 2012, I work as an Assistant Professor at the University of Tsukuba, Department of Computer Sciences. I is a member of the Mathematical Modeling Laboratory (research on numerical algorithms for Neural Networks), and the Center for Artificial Intelligence Research (research on applications of Artificial Intelligence and Machine Learning). Other research topics I am interested in are: Evolutionary Computation Theory (specially auto-adaptive systems), Artificial Life, and Game Programming.

I collaborate with the Knowledge Systems Laboratory, the Institute of Petroleum Engineering at the University of Edinburgh, and the Department of Computer Science at the National University of Brasilia.

Among non-research activities, I teach lectures on Experimental Design and Competitive Programming, I coordinate short term student exchange programs and international collaborations at the Computer Science department, I coach for the ACM ICPC teams at Tsukuba University, and I organize game programming workshops for high school students.


My research interests involve Artificial Intelligence and Artificial life. In particular, I'm interested in applications of Artificial Intelligence techniques for modeling, in the concept of software agents as artificial life forms, and in the use of computational intelligence for entertainment and self-expression.

I am also a proponent of Free Software, Open Science, Creative Commons and other initiatives for the democratization of knowledge. I'm interested in learning more about the role of information sciences in social issues, and what we can do to help.

Finally, I am a big fan of zombies.
